    Abstract: A single volume soft sensor capable of sensing real-time continuous contact and stretching. A low-cost and an easy method to fabricate such piezoresistive elastomer-based soft sensors for instant interactions is also provided. An electrical impedance tomography (EIT) technique is employed to estimate changes of resistance distribution on the sensor caused by fingertip contact. To compensate for the rebound elasticity of the elastomer and achieve real-time contact sensing, an adaptive baseline update for EIT is utilized. The baseline updates are triggered by fingertip contact and movement detections.

The resulting acousto-optic system can be used to determine damage initiation, progressive damage development, identify critical regions and make lifetime predictions of the tested specimen.

  • Patent number: 10482758
    Abstract: A control panel is used to monitor events within a security system or other automation system. In the event an intruder enters a physical location, the intruder may attempt to damage the control panel to disrupt its operation. One or more sensors of the control panel may detect disruption in the operation of the control panel. Example sensors may detect an impact force, sudden acceleration, removal from a mounted location, or disruption of communication with an input/output element, such as a display device. When an event is detected at the control panel itself, the control panel can send a signal to a remote service provider, and the remote service provider can follow-up with the customer. The control panel and/or remote service provider may also determine when the control panel loses partial or complete power loss to identify the disruption as a potential crash-and-smash entry.

  • Patent number: 10464476
    Abstract: Lighting may be provided using light sources such as lighting systems with arrays of light-emitting diodes. A lighting system may be integrated into a seat, a door panel, a dashboard, or other interior portions of a system such as a vehicle. The interior portions of the vehicle may be illuminated using lighting systems to provide ambient light, to provide custom surface textures and other decorative patterns, to provide icons, text, and other information, and to provide custom gauges and other illuminated regions. Illuminated regions may overlap sensors such as capacitive touch sensors, force sensors, and other sensors. The light-emitting diodes in a lighting system may supply light that passes through openings in a cover layer. The layer may be formed from fabric, leather, or other materials. Lens structures may guide light through the openings.

  • Patent number: 10434660
    Abstract: Certain aspects relate to systems and techniques for surgical robotic arm admittance control. In one aspect, there is provided a system including a robotic arm and a processor. The processor may be configured to determine a force at a reference point on the robotic arm based on an output of a torque sensor and receive an indication of a direction of movement of the reference point. The processor may also determine that a component of the force is in the same direction as the direction of movement of the reference point, generate at least one parameter indicative of a target resistance to movement of the robotic arm, and control the motor, based on the at least one parameter, to move the robotic arm in accordance with the target resistance.

  • Patent number: 10283557
    Abstract: Various approaches are discussed for using four-side buttable CMOS tiles to fabricate detector panels, including large-area detector panels. Fabrication may utilize pads and interconnect structures formed on the top or bottom of the CMOS tiles. Electrical connection and readout may utilize readout and digitization circuitry provided on the CMOS tiles themselves such that readout of groups or sub-arrays of pixels occurs at the tile level, while tiles are then readout at the detector level such that readout operations are tiered or multi-level.
